This application is a divisional application of U.S. patent application Ser. No. 10/826,272 filed on Apr. 19, 2004 (pending). The entire disclosure of U.S. patent application Ser. No. 10/826,272 is hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention generally relates to an electrical bicycle shift control device. More specifically, the present invention relates to an electrical shift control assembly, which has at least one electrical shift control device clamped onto the handlebar to provide at least one additional location to control shifting.

2. Background Information

Bicycling is becoming an increasingly more popular form of recreation as well as a means of transportation. Moreover, bicycling has become a very popular competitive sport for both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle. One component that has been extensively redesigned is the bicycle shifting mechanism.

In the past, the operating force applied by the fingers to a shift control lever was transmitted to the drive component of a bicycle shifting mechanism by a cable that was fixed at one end to the control lever. More recently, electric switches mounted on the handlebar have been used instead of mechanical control levers in order to operate the bicycle shifting mechanism. For example, as shown in Japanese Laid-Open Patent Application No. 5-338581 and U.S. Pat. No. 5,358,451, a plurality of electric switches may be provided at a plurality of handlebar locations in order to allow for quicker shifts and to enhance responsiveness. However, it is often inconvenient to move the hands around the handlebar to operate the brakes and the electric switches depending on the hand position at a given time. Additionally, these typical braking devices and/or electric switches can be difficult or at least cumbersome to assemble and install on the bicycle. Furthermore, these typical braking devices and/or electric switches can be unsightly.

In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved electrical bicycle shift control assembly with an improved electrical shift control device. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Selected embodiments of the present invention will now be explained with reference to the drawings It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

Referring initially to FIGS. 1 and 2, a bicycle 10 is illustrated with a pair of electrical shift/brake control devices 12R and 12L (only one shown in FIG. 1) and a pair of additional electrical shift control devices 13R and 13L (only one shown in FIG. 1) mounted on a bicycle handlebar 14 in accordance with the present invention. The electrical shift/brake control devices 12R and 12L and the additional electrical shift control devices 13R and 13L form parts of a brake and shift control system or assembly of the bicycle 10 in accordance with the present invention. The additional electrical shift control devices 13R and 13L are preferably mounted to a central transverse portion T of the handlebar 14 in accordance with the present invention, as explained below. The transverse portion T is preferably straight (i.e., linear).

The right and left hand side control devices 12R and 12L are essentially identical in construction and operation, except that that are mirror images. Moreover, the parts of right and left hand side control devices 12R and 12L that are identical or mirror images will be given the same reference numerals for the sake of brevity. The additional shift control devices 13R and 13L are also essentially identical in construction and operation, except that that are mirror images. Thus, only one of the shift control devices 13R and 13L will be discussed and illustrated herein. Moreover, the parts of right and left hand side shift control devices 13R and 13L that are identical or mirror images will be given the same reference numerals for the sake of brevity.

The right hand side control device 12R is operatively coupled to a rear derailleur 16 via a bicycle computer unit 24, while the left hand side control device 12L is operatively coupled to a front derailleur 20 via the bicycle computer unit 24. The additional right hand side shift control device 13R is also operatively coupled to the rear derailleur 16 via the bicycle computer unit 24, while the additional left hand side shift control device 13L is also operatively coupled to the front derailleur 20 via the bicycle computer unit 24. Additionally, the right hand side control device 12R is preferably directly mechanically coupled to a rear brake device 18 via a brake cable 18 a, while the left hand side control device 12L is preferably directly mechanically coupled to a front brake device 22 via a brake cable 22 a. The cycle computer unit 24 also forms a part of the brake and shift control system or assembly of the bicycle 10 mentioned above. The cycle computer unit 24 operates the rear and front derailleurs 16 and 20 via electrical wires 16 a and 20 a in a conventional manner. Preferably, at least one of the additional electrical shift control devices 13R and 13L supports the cycle computer unit 24, as explained below.

The brake and shift control system of the bicycle 10 controls the rear derailleur 16, the rear brake device 18, the front derailleur 20 and the front brake device 22. In particular, the brake and shift control system of the bicycle 10 mechanically controls the rear brake device 18 and the front brake device 22, while the brake and shift control system of the bicycle 10 electronically controls the rear derailleur 16 and the front derailleur 20. Thus, the brake and shift control system of the bicycle 10 preferably includes a conventional mechanical brake control system as well as an electrical shift control system or assembly in accordance with the present invention, as explained below.

Since most of the parts of the bicycle 10 are well known in the art, the parts of the bicycle 10 will not be discussed or illustrated in detail herein, except for the parts relating to the present invention. Moreover, various conventional bicycle parts, which are not illustrated and/or discussed in detail herein, can also be used in conjunction with the present invention. In other words, it will be apparent to those skilled in the art from this disclosure that various modifications can be made to the various parts of the bicycle 10 without departing from the present invention, as needed and/or desired.

Referring now to FIGS. 2-11, the additional electrical shift control devices 13R and 13L will now be discussed in more detail. Basically, each of the shift control devices 13R and 13L includes a handlebar mounting portion 30 and an electrical shift control switch portion 32. The handlebar mounting portion 30 is configured to be clamped onto the transverse portion T of the handlebar 14. The electrical shift control switch portion 32 is detachably coupled to the handlebar mounting portion 30 via a protrusion and recess arrangement and a threaded fastener or screw 34. The parts of the protrusion and recess arrangement will be discussed in more detail below.

For the sake of convenience, the “electrical shift control switch portion 32” will also simply be referred to as “the electrical switch portion 32” hereinafter. When the fastener 34 is removed, the electrical (shift control) switch portions 32 can be removed from the handlebar mounting portions 30 without removing the handlebar mounting portions 30 from the handlebar 14. The electrical (shift control) switch portions 32 of the shift control devices 13R and 13L are utilized by the rider to shift the rear derailleur 16 and the front derailleur 20, respectively.

Referring mainly to FIGS. 2-7, the handlebar mounting portion 30 basically includes a tubular clamping member 36, a switch mounting structure 38 and a computer support leg 40. The switch mounting structure 38 is fixedly coupled to the tubular clamping member 36, while the computer support leg 40 is removably coupled to the tubular clamping member 36. The electrical switch portion 32 is detachably coupled to the switch mounting structure 38 of the handlebar mounting portion 30, as explained below in more detail. Preferably, the switch mounting structure 38 and the tubular clamping member 36 are integrally formed together as a one-piece, unitary member of a lightweight, rigid material such as cast aluminum or hard plastic.

The tubular clamping member 36 includes a first attachment end 36 a, a second attachment end 36 b and a band section 36 c extending between the attachment ends 36 a and 36 b. A bolt 42 a and a nut 42 b couple the attachment ends 36 a and 36 b together to mount the tubular clamping member 36 on the handlebar 14. Specifically, the nut 42 b is non-rotatably coupled to the second attachment end 36 b, while the bolt 42 a is rotatably coupled to the first attachment end 36 a. Thus, rotation of the bolt 42 a causes the attachment ends 36 a and 36 b to move toward each other to reduce the effective inner diameter of a curved mounting surface 36 d of the band section 36 c. The curved surface 36 d contacts the outer surface of the handlebar 14. Accordingly, the tubular clamping member 36 is clamped onto the handlebar 14.

The computer support leg 40 is mounted on the bolt 42 a between the attachment ends 36 a and 36 b. Specifically, a pair of resilient members 44 (e.g. rubber washers) are arranged on opposite sides of the computer support leg 40 such that the support leg 40 is securely held between opposing surfaces of the attachment ends 36 a and 36 b on the bolt 42 a. The resilient members 44 are deformable such that the computer support leg 40 and the members 44 do not interfere with securing the tubular clamping member 36 onto the handlebar 14. In other words, the resilient members will deform to become effectively thinner if needed in order to securely clamp the tubular clamping member 36 onto the handlebar 14.

The computer support leg 40 basically includes a bicycle attachment end 40 a, a computer attachment end 40 b and a bent section 40 c disposed between the bicycle attachment end 40 a and the computer attachment end 40 b. The bicycle attachment end 40 a has opposed flat surfaces with a through hole extending therebetween for receiving the bolt 42 a. The computer attachment end 40 b is releasably coupled to the cycle computer by a snap-fit or using fasteners (not shown) in a conventional manner. The bent section 40 c is configured and arranged such that the bicycle computer unit 24 is longitudinally offset from the band section 36 c of the tubular clamping portion 36.

In the illustrated embodiment, the computer support legs 40 of the additional shift control devices 13R and 13L are preferably integrally formed together as a one-piece, unitary computer support member 41 that has a substantially U-shaped configuration, as best seen in FIGS. 2 and 3. Thus, the computer attachment end 40 b of one of the computer support legs 40 is preferably common to the other computer support leg 40. However, it will be apparent to those skilled in the art from this disclosure that the computer support legs 40 could be formed as separate members, and/or that one of the computer support legs 40 could be completely eliminated if needed and/or desired. If one of the computer support legs 40 is eliminated, it will be apparent to those skilled in the art from this disclosure that the single computer support leg 40 could be integrally formed with the tubular clamping member 36 of one of the shift control devices 13R and 13L, as discussed below with reference to another embodiment of the present invention. In any case, the computer support leg or legs 40 are preferably configured and arranged such that the bicycle computer unit 24 is longitudinally offset from the band sections 36 c along the handlebar 14, as best seen in FIGS. 2 and 3.

The switch mounting structure 38 basically includes a pair of longitudinal rails 46 extending from an abutment member 48 to form a substantially T-shaped longitudinal recess 50 with a single open end. A hexagonal shaped cutout 52 preferably extends through the abutment member 48, the longitudinal recess 50 and partially through the rails 46, as best seen in FIGS. 9 and 11. The nut 42 b is received in the cutout 52 prior to attaching the electrical switch portion 32 to the handlebar mounting portion 30. A stepped through bore 48 a is formed in the abutment member 48 to receive the fastener 34. The switch mounting structure 38 (i.e., the T-shaped recess 50) preferably forms part of the protrusion and recess arrangement, which couples the handlebar mounting portion 30 with the electrical switch portion 32 mentioned above.

The bicycle computer unit 24 basically includes a computer housing 54 with a display screen 56. The display screen is preferably an LCD display screen. The internal workings of the bicycle computer unit 24 are well known in the art. Thus, the bicycle computer unit 24 will not be discussed and/or illustrated in detail herein, except as related to the present invention. The computer housing 54 basically encloses the internal parts of the bicycle computer unit 24 such as the CPU, ROM, RAM, I/O interface, etc. The bicycle computer unit 24 can be powered by an internal power supply (e.g. a battery) or externally as needed and/or desired. The computer unit 24 receives electrical signals from the various electrical switches of the bicycle 10, processes the signals, and then operates/actuates (i.e., via electrical signals sent through the cords 16 a and 20 a) the rear and front derailleurs 16 and 20 in a conventional manner.

The computer housing 54 also is utilized to support the bicycle computer unit 24 by the computer support legs 40. In particular, the computer housing 54 includes a bottom surface 54 a configured to be coupled to the computer attachment end 40 b of the computer support legs 40 as best seen in FIG. 2. In particular, the bottom surface 54 a is preferably configured to be snap fit with the computer attachment end 40 b, or configured with threaded holes to be attached via fasteners in a conventional manner. In the illustrated embodiment, the computer attachment end 40 b of the computer support leg 40 and the bottom surface 54 a are preferably configured to be snap-fitted together in a conventional manner. Accordingly, the precise structure of the computer attachment end 40 b of the computer support leg 40 as well as the bottom surface 54 a will not be discussed and/or illustrated in detail herein, except as related to the present invention.

Referring to FIGS. 2-14, the electrical switch portion 32 will now be explained in more detail. The electrical switch portion 32 is electrically coupled to an electrical cord 58 having an electrical conductor 58 a, an electrical conductor 58 b and an electrical conductor 58 c. The electrical cord 58 is electrically coupled to the bicycle computer unit 24. The electrical switch portion 32 basically includes a housing 60, an operating member 61 and an electrical contact assembly 62, as seen in FIGS. 7 and 8. The operating member 61 is rotatably coupled to the housing 60 and operatively coupled to the electrical contact assembly 62 to be selectively moved relative to the handlebar mounting portion 30 (i.e., to first and second actuating positions from a neutral, rest position). The electrical contact assembly 62 is mounted within the housing 60 and is configured and arranged to be operated by the operating member 61.

The electrical contact assembly 62 is electrically coupled to the electrical contacts 58 a-58 c of the electrical cord 58. As explained below in more detail, the electrical switch portion 32 (i.e., the operating member 61) has a first actuating or upshift position, a second actuating or downshift position and a neutral or rest position located between the first and second actuating positions as best seen in FIGS. 12-14. Accordingly, the electrical switch portion 32 (i.e., the operating member 61) can be utilized for both upshifting and downshifting one of the derailleurs 16 and 20. The first and second actuating positions are arranged on opposite sides of the neutral position.

Of course, it will be apparent to those skilled in the art from this disclosure that the upshifting and downshifting positions of the operating member 61 could be reversed if needed and/or desired, depending on how the cord 58 is connected. In other words, the additional electrical shift control devices 13R and 13L are preferably identical, except for the way in which the operating members 61 are configured. Specifically, the operating members 61 are mounted such that they are mirror images of each other. However, the cords 58 can be connected in the same manner or differently so the additional electrical shift control devices 13R and 13L operate in the same manner or slightly different manners. For example, one of the additional electrical shift control devices 13R and 13L can be connected to its respective cord 58 such that a particular actuating movement (e.g., clockwise movement of the operating member 61) produces an upshift, while the other of the additional electrical shift control devices 13R and 13L can be connected to its respective cord 58 such that a particular actuating movement (e.g., clockwise movement of the operating member 61) produces a downshift, and vice versa.

Preferably, the housing 60 is constructed of two pieces. For example, the housing 60 as illustrated, includes a rectangular cup-shaped base element 64 and a rectangular cover element 66 that is coupled to the base element 64. The base element 64 and cover element 66 are each preferably constructed of a hard rigid material such as a hard rigid plastic or metal material. The electrical contact assembly 62 is housed within the housing 60 between the base element 64 and the cover element 66 and electrically coupled to the electrical conductors 58 a-58 c of the electrical cord 58, as mentioned above. Specifically, the electrical contact assembly 62 is preferably mounted in the base element 64 as seen in FIG. 8. After all electrical connections between the electrical contact assembly 62 and the cord 58 are made, the cover element 66 is fixedly coupled to the base element (e.g., by a snap fit, glue, fasteners, or any other suitable attachment technique).

Preferably, the base element 64 includes a wire opening 64 a that is configured and arranged to receive a rubber wire mounting member 59 that has the cord 58 extending outwardly therethrough as best seen in FIG. 7. The wire mounting member 59 seals the wire opening 64 a so that a filler material such an epoxy resin filler material can be retained in the area B after all electrical connections between the cord 58 and the electrical switch portion 32 are made.

The cover element 66 includes a substantially T-shaped longitudinal projection 68 with a longitudinally extending threaded blind bore 68 a extending from an end surface 68 b that is configured to threadedly receive the threaded fastener 34 therein. The projection 68 preferably has a cross-sectional shape identical or substantially identical to the cross-sectional shape of the recess 52 of the switch mounting structure 38. In other words, the projection 68 is configured to be slid into the recess 52 until the end surface 68 b of the projection 68 contacts the abutment member 48. The fastener 34 is then inserted through the hole 48 a of the abutment member 48 into the threaded hole 68 a to couple the electrical switch portion 32 to the handlebar mounting portion 30. In other words, after the fastener 34 couples the electrical switch portion 32 to the handlebar mounting portion 30, the electrical switch portion 32 is non-movable relative to the handlebar mounting portion 30. However, if the fastener 34 is subsequently removed, the electrical switch portion 32 is slidable relative to and removable from the handlebar mounting portion 30, without removing the handlebar mounting portion 30 from the handlebar 14.

The T-shaped protrusion 68 and the T-shaped recess 52 form parts of the protrusion and recess arrangement mentioned above. Of course, it will be apparent to those skilled in the art from this disclosure that other types of protrusion and recess arrangements can be used in conjunction with the present invention. For example, the protrusion and recess arrangement illustrated herein could be reversed if needed and/or desired. Furthermore, it will be apparent to those skilled in the art from this disclosure that the protrusion and recess arrangement illustrated herein could be modified without departing from the present invention. For example, the fastener 34 could be eliminated and the protrusion and recess arrangement illustrated herein could be provided with a snap-fit retaining structure (i.e., a bulge/detent arrangement) rather than using a separate fastener.

The operating member 61 protrudes out from the housing 60 such that rotational movement of the operating member 61 causes the electrical contact assembly 62 to move from a normal or rest position to one of the two actuating positions as explained below. The operating member 61 basically has a knob or dial-shaped actuator 70, a pivot shaft 72 and a toggle member 74. The actuator 70 is fixedly attached the outer end of the pivot shaft 72 by a set pin 76 that contacts a flat portion of the outer end of the pivot shaft 72. The inner end of the pivot shaft 72 has the toggle member 74 fixedly coupled thereto. Thus, rotation of the actuator 70 by the rider causes the pivot shaft 72 and the toggle member 74 to rotate therewith.

Preferably, a bearing assembly 78 is positioned between the housing 60 and the pivot shaft 72 such that the operating member 61 pivots or rotates smoothly about a rotational operating axis or pivot axis X. Preferably, the pivot axis X of the operating member 61 is non-parallel to a center axis C of the transverse portion T of the handlebar 14. The pivot axis X preferably intersects the curved mounting surface 36 d of the tubular clamping portion 36 as best seen in FIG. 7.

A biasing element (coil spring) 79 is positioned between the housing 60 and the toggle member 74 to normally bias the toggle member 74, and thus, the operating member 61 to the normal rest or neutral position from the first and second actuating positions. In particular, one end of the spring 79 is preferably received in an axial hole (not shown) of the base element 64, while the other end of the spring 79 is preferably received in an axial hole (not shown) of the toggle member 74. The axial holes (not shown) and the spring 79 are preferably arranged and configured to bias the operating member 61 to the neutral rest position from the first and second actuating positions. The spring 79 preferably has a coiled portion with at least two coils.

The toggle member 74 has an annular mounting portion 74 a with a radially extending projection 74 b extending outwardly from the mounting portion 74 a. The mounting portion 74 a preferably has a non-circular opening with a portion of the pivot shaft 72 non-rotatably received therein. The projection 74 b engages the electrical contact assembly 62 in response to rotation of the operating member 61, as explained below.

The actuator 70 basically includes a dial element 70 a, at least one projection 70 b and a pair flange elements 70 c. The projection 70 b extends radially outwardly from the outer edge of the dial element 70 a to facilitate engagement with the rider's thumb or fingers. The dial element 70 a has a textured outermost edge 70 d with a frustaconical surface 70 e extending therefrom as best seen in FIGS. 3-6. The flange elements 70 c project from the frustaconical surface 70 e. The textured outermost edge 70 d as well as the flange elements 70 c are configured to facilitate engagement with the riders thumb or fingers. The flange elements 70 c are circumferentially spaced in opposite directions from the projection 70 b. The projection 70 b preferably has a maximum radial dimension measured relative to the textured outermost edge 70 d that is about the same as a maximum radial dimension of the dial element 70 a measured between the pivot axis X and the outermost edge 70 d.

As seen in FIGS. 12-14, the electrical contact assembly 62 preferably includes a common contact bar 80, a first stationary contact 82, a first movable (downshift) contact 84, a second stationary contact 86, a second movable (upshift) contact 88 and a biasing element 90 formed of a pair of leaf springs 90 a and 90 b. Generally, when the electrical switch portion 32 (i.e., the operating member 61) is in the rest/neutral position, the projection 74 b of the toggle member 74 (i.e. of the operating member 61) is located centrally between the first and second movable contacts 84 and 88. In particular, the biasing element 90 holds the toggle member 74 of the operating member 61 in the rest position between the first and second movable contacts 84 and 88. The spring 79 also holds the toggle member 74 in the rest position.

However, when the rider rotates the actuator 70 of the operating member 61, this causes the pivot shaft 72 to pivot the toggle member 74 such that the projection 74 b is pressed against one of the movable contacts 84 and 88. This pivotal movement of the toggle member 74 causes one of the movable contacts 84 and 88 to be deflected such that the deflected movable contact directly contacts the corresponding one of the stationary contacts 82 and 86. More specifically, when the actuator 70 of the operating member 61 is rotated in a clockwise direction as seen by the rider (FIG. 13), the toggle member 74 deflects the first movable contact 84 such that the first movable contact 84 contacts the first stationary contact 82. The rider's view of the actuator is reversed from that illustrated in FIGS. 12-14. Thus, an electrical connection is made between the first stationary contact 82 and the first movable contact 84 such that a shift control signal is sent to the cycle computer unit 24, which in turn operates one of the derailleurs 16 and 20 to cause a shift to occur. If the actuator 70 of the operating member 61 is rotated in a counterclockwise direction as seen by the rider (FIG. 14), an opposite shift of one of the derailleurs 16 and 20 occurs. In particular, rotation of the actuator 70 of the operating member 61 causes the toggle member 74 to deflect the second movable contact 88 against the second stationary contact 86 to result in an electrical connection therebetween. The rider's view of the actuator is reversed from that illustrated in FIGS. 12-14. This electrical connection causes a control signal to be inputted into the cycle computer unit 24 such that a shift control signal is sent to one of the derailleurs 16 and 20.

The cycle computer unit 24 is electrically coupled to the electrical switch portion 32 via the electrical cord 58, as mentioned above. In particular, the first electrical conductor 58 a of the electrical cord 58 is electrically connected to the common contact bar 80. The second electrical conductor 58 b of the electrical cord 58 is electrically connected to the first stationary contact 82, while the third electrical conductor 58 c of the electrical cord 58 is electrically connected the second stationary contact 86. When the first contacts 82 and 84 are touching, the first conductor 58 a is electrically connected to the second electrical conductor 58 b to transmit a downshift control signal to the cycle computer unit 24. On the other hand, when the second contacts 86 and 88 are touching, the first conductor 58 a is electrically connected to the third electrical conductor 58 c to transmit an upshift control signal to the cycle computer unit 24.

Basically, the first stationary contact 82 includes a wiring plate 82 a and a contact element 82 b with a first stationary engagement surface. The first stationary contact 82 is constructed of a rigid electrical conductive material such as those known in the art. The first stationary contact 82 is fixedly secured to the housing 60 when the base element 64 and the cover element 66 are fixedly coupled together. The second electrical conductor 58 b of the electrical cord 58 is electrically connected to the first stationary contact 82 by soldering or otherwise attaching the conductor to the wiring plate 82 a.

The first movable contact 84 includes a first mounting element 84 a with a contact element 84 b mounted on one end of the first mounting element 84 a, and a second mounting element 84 c coupled to the other end of the first mounting element 84 a. The elements 84 a-84 c of the first movable contact 84 are constructed of rigid electrical conductive materials such that an electrical path is created by these elements. The first mounting element 84 a is swingably mounted to the common contact bar 80 and the second mounting element 84 c such that the first mounting element 84 a moves between a normal or rest position and an actuating position in response to rotation of the actuator 70 of the operating member 61. Thus, the contact element 84 b has a movable engagement surface that is arranged and configured to move with the first mounting element 84 a when the operating member 61 is operated. In other words, the movable engagement surface of the contact element 84 b of the first movable contact 84 selectively moves into electrical engagement with the first stationary engagement surface of the contact element 82 b of the first stationary contact 82 upon clockwise rotation of the actuator 70 of the operating member 61 to the first actuating position as seen by the rider (FIG. 13).

The second mounting element 84 c is coupled between the common contact bar 80 and the free end of the first mounting element 84 a to control the swinging or pivotal movement of the first mounting element 84 a. Thus, the second mounting element 84 c is pivotally mounted at its first end to the common contact bar 80 and at its second end to the first mounting element 84 a. One end of the leaf spring 90 a of the biasing element 90 is coupled to the common contact bar 80, while the other end of the leaf spring 90 a is coupled to the first mounting element 84 a such that the first and second mounting elements 84 a and 84 c urge the toggle member 74 of the operating member 61 to the center rest position and the contact element 84 b out of engagement with the stationary contact element 82 b.

This arrangement of the leaf spring 90 a together with the first and second mounting elements 84 a and 84 c form an audible clicking element that is configured and arranged to produce an audible sound that occurs upon selective movement of the operating member 61 to the first actuating position. In other words, an audible clicking sound occurs simultaneous with the movable engagement surface of the contact element 84 b engaging the stationary engagement surface of the contact element 82 b.

Basically, the second stationary contact 86 includes a wiring plate 86 a and a contact element 86 b with a second stationary engagement surface. The second stationary contact 86 is constructed of a rigid electrical conductive material such as those known in the art. The second stationary contact 86 is fixedly secured to the housing 60 when the base element 64 and the cover element 66 are fixedly coupled together. The third electrical conductor 58 c of the electrical cord 58 is electrically connected to the second stationary contact 86 by soldering or otherwise attaching the conductor to the wiring plate 86 a.

The second movable contact 88 includes a first mounting element 88 a with a contact element 88 b mounted on one end of the first mounting element 88 a, and a second mounting element 88 c coupled to the other end of the first mounting element 88 a. The elements 88 a-88 c of the second movable contact 88 are constructed of rigid electrical conductive materials such that an electrical path is created by these elements. The first mounting element 88 a is swingably mounted to the common contact bar 80 and the second mounting element 88 c such that the first mounting element 88 a moves between a normal or rest position and an actuating position in response to rotation of the actuator 70 of the operating member 61. Thus, the contact element 88 b has a movable engagement surface that is arranged and configured to move with the first mounting element 88 a when the operating member 61 is operated. In other words, the movable engagement surface of the contact element 88 b of the second movable contact 88 selectively moves into electrical engagement with the second stationary engagement surface of the contact element 86 b of the second stationary contact 86 upon counterclockwise rotation of the actuator 70 of the operating member 61 to the second actuating position as seen by the rider (FIG. 14).

The second mounting element 88 c is coupled between the common contact bar 80 and the free end of the first mounting element 88 a to control the swinging or pivotal movement of the first mounting element 88 a. Thus, the second mounting element 88 c is pivotally mounted at its first end to the common contact bar 80 and at its second end to the first mounting element 88 a. One end of the leaf spring 90 b of the biasing element 90 is coupled to the common contact bar 80, while the other end of the leaf spring 90 b is coupled to the first mounting element 88 a such that the first and second mounting elements 88 a and 88 c urge the toggle member 74 of the operating member 61 to the center rest position and the contact element 88 b out of engagement with the stationary contact element 86 b.

This arrangement of the leaf spring 90 b together with the first and second mounting elements 88 a and 88 c form an audible clicking element that is configured and arranged to produce an audible sound that occurs upon selective movement of the operating member 61 to the second actuating position. In other words, an audible clicking sound occurs simultaneous with the movable engagement surface of the contact element 88 b engaging the stationary engagement surface of the contact element 86 b.

Referring now to FIGS. 1, 2, 15 and 16, the electrical shift/brake control devices 12R and 12L will now be explained in more detail. Basically, each of the electrical shift and brake control devices 12R and 12L includes a support member or brake lever bracket 130, a brake lever 132, and a pair of electrical shift control switches 136. In the control device 12R, the brake cable 18 a is fixedly coupled to the brake lever 132 such that the inner wire is pulled when the rider squeezes the brake lever 132. Likewise, the brake cable 22 a is fixedly coupled to the brake lever 132 of the control device 12L such that the inner wire is pulled when the rider squeezes the brake lever 132.

As best seen in FIG. 2, the cycle computer unit 24 is electrically coupled to the first and second electrical shift control switches 136 and 138 of each of the control devices 12R and 12L via a pair of electrical cords 154.

In particular, each of the electrical cords 154 has a pair of first electrical conductors 154 a, a pair of second electrical conductors 154 b and a pair of third electrical conductors 154 c, which are electrical coupled to the electrical shift control switches 136 and 138. Each cord 154 connects one of the electrical shift control switches 136 and the electrical shift control switches 138 to the bicycle computer 24. When one of the first conductors 154 a is electrically connected to one of the second electrical conductors 154 b via the electrical shift control switch 136 or 138, then a downshift signal is transmitted to the cycle computer unit 24. On the other hand, when one of the first conductors 154 a is electrically connected to one of the third electrical conductors 154 c via the electrical shift control switch 136 or 138, then an upshift signal is transmitted to the cycle computer unit 24. The cycle computer unit 24, the electrical switch portions 32, the first electrical shift control switches 136 and 138 form parts of the electrical shift control system of the present invention.

Basically, each of the electrical shift control switches 136 and 138 includes a housing 160, an operating member 161 and an electrical contact assembly 162, as seen in FIG. 22. The operating member 161 is rotatably coupled to the housing 160 and operatively coupled to the electrical contact assembly 162. The electrical contact assembly 162 mounted within the housing 160 and configured and arranged to be operated by the operating member 161. The construction of the electrical contact assembly 162 is the same as the electrical contact assembly 62, discussed above. Thus, the electrical shift control switches 136 and 138 will not be discussed or illustrated in detail herein. Rather the construction and operation of the electrical shift control switches 136 and 138 can be readily determined from the description of the electrical contact assembly 62, discussed above.
